Definitely check out INFRA (https://store.steampowered.com/app/251110/INFRA/) if you're into exploration puzzle games. I absolutely love the atmosphere in this game. It's on sale right now!

Supraland is the game you want - it fits all your criteria except the most important one: it’s currently Unsupported on SteamDeck. I found reports of people getting it to work but not without some fiddling. It has a sequel, though, which is just as good and which is Verified. The sequel is called Supraland: Six Inches Under.
The first game is an indie gem made mostly by one guy but it is very polished. This sequel was made by a small team. Don’t let the cute graphics throw you - it’s not a kids game. It’s a first-person open world metroidvania (not really a shooter, though there are enemies you’ll be hitting) with gameplay reminiscent of Portal, Zelda, and Metroid. Currently on sale for 40% off ($11.99). About 8-20 hours long.
Portal reloaded and Tony hawk pro skater 3(ps2 emulator) are super chill games I can pickup and put down any time.
Sea of Stars. Nice RPG, inspired by Chrono Trigger. I've been playing that for some nights on my deck. Easy to engage, nice story and difficulty can be adjusted depending on how much time you want to invest.
I'm in a similar situation to you, except that I've got a Switch rather than a Steam Deck.
I've been playing Lego Jurassic World, and it should tick all your boxes. I've got no idea how the Lego games work on the Deck though.
